From: root <r...@arsenal.linuxperf9025.net> With these modifications we can now start virtagent via a bool option to the virtproxy chardev. For example:
qemu -chardev virtproxy,id=va_id,virtagent=on and then passing the chardev id to whatever device we're using for the transport (virtio/isa serial) Signed-off-by: Michael Roth <mdr...@linux.vnet.ibm.com> --- qemu-char.c | 24 ++++++++++++++++++++++++ qemu-config.c | 3 +++ 2 files changed, 27 insertions(+), 0 deletions(-) diff --git a/qemu-char.c b/qemu-char.c index e318acb..9f5efac 100644 --- a/qemu-char.c +++ b/qemu-char.c @@ -1905,6 +1905,8 @@ return_err: /* Virtproxy chardev driver */ #include "virtproxy.h" +#include "virtagent.h" +#include "virtagent-daemon.h" static int vp_chr_write(CharDriverState *chr, const uint8_t *buf, int len) { @@ -1925,6 +1927,8 @@ static CharDriverState *qemu_chr_open_virtproxy(QemuOpts *opts) { CharDriverState *chr = qemu_mallocz(sizeof(CharDriverState)); VPDriver *drv = vp_new(VP_CTX_CHARDEV, chr, 0, 0); + int ret; + bool enable_virtagent; chr->opaque = drv; chr->chr_write = vp_chr_write; @@ -1937,10 +1941,30 @@ static CharDriverState *qemu_chr_open_virtproxy(QemuOpts *opts) * client/server, which will add it's oforwards/iforwards * using using virtproxy API calls directly */ + enable_virtagent = qemu_opt_get_bool(opts, "virtagent", 0); + if (enable_virtagent) { + /* outbound RPCs */ + ret = va_client_init(drv, true); + if (ret) { + fprintf(stderr, "error enabling virtagent client"); + goto fail; + } + /* inbound RPCs */ + ret = va_server_init(drv, true); + if (ret) { + fprintf(stderr, "error enabling virtagent server"); + goto fail; + } + } /* for "info chardev" monitor command */ chr->filename = NULL; return chr; + +fail: + qemu_free(drv); + qemu_free(chr); + return NULL; } /***********************************************************/ diff --git a/qemu-config.c b/qemu-config.c index 52f18be..374182b 100644 --- a/qemu-config.c +++ b/qemu-config.c @@ -146,6 +146,9 @@ static QemuOptsList qemu_chardev_opts = { },{ .name = "signal", .type = QEMU_OPT_BOOL, + },{ + .name = "virtagent", + .type = QEMU_OPT_BOOL, }, { /* end of list */ } }, -- 1.7.0.4
